Filed: 1974-03-26
Abstract: 1457587 Automatic current regulation RCA CORPORATION 26 March 1974 [30 March 1973] 13383/74 Heading G3X A current source circuit includes a field effect transistor with drain and gate electrodes directly coupled, and source and substrate electrodes connected together through a resistive path. A supply voltage is connected across the substrate and drain electrodes, and the drain current is sensed and used to control an output current. As shown in Fig. 6, the source-drain path of an FET 101 is connected in series with a resistor 111 and diode-connected transistor 625 across a resistor 519 forming, together with a resistor 517, a voltage divider across a D.C. source 513 . The FET has its gate and drain electrodes directly connected, and its substrate electrode is connected to the source electrode through resistors 517 and 111, so that the biasing potential between the source and substrate electrodes varies automatically if the supply voltage varies, or if the FET charac-  teristics change with temperature, in a sense and at a rate such that the current at the drain electrode remains constant. This current is sensed by the transistor 625 and supplied to a load 623 by another transistor 627 forming a current mirror 621. In a modification, Fig. 7 (not shown), transistors 625, 627 are replaced by further FET'S. In another arrangement, a diode-connected FET is connected between the FET 101 and transistor 625, Fig. 8 (not shown).
